Programming an estimation command in Stata: Writing a Java plugin

This post is the fourth in a series that illustrates how to plug code written in another language (like C, C++, or Java) into Stata. This technique is known as writing a plugin or as writing a dynamic-link library (DLL) for Stata.

In this post, I write a plugin in Java that implements the calculations performed by mymean_work() in mymean11.ado, discussed in Programming an estimation command in Stata: Preparing to write a plugin, and I assume that you are familiar with that material.

This post is analogous to Programming an estimation command in Stata: Writing a C plugin and to Programming an estimation command in Stata: Writing a C++ plugin. The differences are due to the plugin code being in Java instead of C or C++. I do not assume that you are familiar with the material in those posts, and much of that material is repeated here.

This is the 32nd post in the series Programming an estimation command in Stata. See Programming an estimation command in Stata: A map to posted entries for a map to all the posts in this series. Read more…

This post is analogous to Programming an estimation command in Stata: Writing a C plugin. The differences are due to the plugin code being in C++ instead of C. I do not assume that you are familiar with the material in that post, and you will find much of it repeated here.

Programming an estimation command in Stata: Preparing to write a plugin

This post is the first in a series that illustrates how to plug code written in another language (like C, C++, or Java) into Stata. This technique is known as writing a plugin or as writing a dynamic-link library (DLL) for Stata.

Plugins can be written for any task, including data management, graphical analysis, or statistical estimation. Per the theme of this series, I discuss plugins for estimation commands.

In this post, I discuss the tradeoffs of writing a plugin, and I discuss a simple program whose calculations I will replace with plugins in subsequent posts.

This is the 29th post in the series Programming an estimation command in Stata. See Programming an estimation command in Stata: A map to posted entries for a map to all the posts in this series. Read more…

Importing Facebook data into Stata

In a previous post, we released a new command to import Twitter data into Stata. We have now added another new command, facebook2stata, that imports Facebook data. To install facebook2stata, type

net install https://www.stata.com/users/kcrow/facebook2stata, replace
